Draw some crude pictures (6)
I believe the answer is:
depict
'draw' is the definition.
('depict' can be a synonym of 'draw')
'some crude pictures' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'DEPICT' can be found hidden inside 'crude pictures'.
(Other definitions for depict that I've seen before include "Portray, represent" , "Make a likeness of" , "Paint" , "Illustrate, describe in detail" , "'Show, portray (6)'" .)
